This guide provides basic informa�on to assist you in ge�ng
started. Go to hseries.oleumtech.com to download the
full User Guide for detailed installa�on and other informa�on.
WARNING!
EXPLOSION HAZARD – THIS DEVICE SHALL BE REMOVED
FROM THE AREA KNOWN TO BE HAZARDOUS IF
MAINTENANCE IS REQUIRED.
TO PREVENT IGNITION OF FLAMMABLE OR COMBUSTIBLE
ATMOSPHERES, DISCONNECT POWER BEFORE SERVICING.
Ensure installa�on of the device meets applicable state
and na�onal electrical code requirements.
The installa�on of the transmi�er should only be performed
by a qualified installer or a factory representa�ve.
2. Power
- Power supply: 20-250 Vac 50/60 Hz or 20-250 Vdc
- Power consump�on: 5 VA (AC) / 2.5 W (DC) Max.,
120 Vac/30 mA or
24 Vdc/75 mA Normal Opera�on
3. Device Controls

- Power indica�on: Red LED
On = Normal, Off = Power failure
- Signal indica�on: Green LED
On = Normal, Off = Alarm
- Alarm modes
High = For overfill protec�on
Normal state: Signal LED on, relay energized
Alarm state: Signal LED off, relay de-energized
Low = For dry run protec�on
Normal state: Signal LED on, relay energized
Alarm state: Signal LED off, relay de-energized
- Sensi�vity (Op�onal) / Factory default set to max
High = Level detec�on closer to the �p of the tuning fork
Low = Level detec�on farther away from the �p of the tuning fork
Tuning Fork Level Switches - HTF174x
